Bleed Hydrolic Clutch Prob? (CB 700 Honda Nighthawk)?

Sounds like you're not pumping fluid, just compressing air when you operate the
clutch lever...

You probably have a big air bubble trapped up near the master cylinder. It
helps to loosen the bolts that hold the master cylinder onto the bar and rotate
the master cylinder and arrange the handlebars so that there is no point in the
hoses that is higher than the point where the hoses attach to the master
cylinder.

Last time I changed fluid in my clutch, I still spent about 15 to 20 minutes
pumping the lever with the master cylinder and hoses arranged as I described
but couldn't build up any pressure in the system until I pulled the slave
cylinder off and used a c-clamp to force the piston all the way back into its
bore to minimize the amount of possible air space down there.

An even better deal is to have a bleeder banjo bolt at the high point. I've
seen them advertised on the internet...

I had the same problem with the '85 CB650SC I picked up this summer, but it
was because the hole in the bottom of the master cylinder was only letting
down a very, very little amount of fluid due to gunk buildup. I cleaned it
out with a needle, and the thing works great now....
